To all whom it may concern:

Be it known that I, ANDREW TAYLOR, a citizen of the United States of America, and a resident of Goldville, county of Laurens, State of South Carolina, have invented certain new and usefui Improvements in Bobbin-Skewers, of which the fol lowing is a full and clear specification.

This invention relates to that class of skewers employed for holding bobbins in roving machines. In this type of skewer, as is well known, the skewers are journaled vertically in a creel, the upper end of the skewer being held loosely in a top bar and the lower pointed end of the skewer being provided with a pointed head whose point rests in a cup or socket formed in or mounted on the bearing rail of the creel. The bobbin is slipped down over the skewer and rests upon an annular shoulder positioned at the lower end of the skewer. An objection to this common form of skewer as now made is that when the skewer carrying the bobbin is accidentally dropped on the floor, as frequently happens in handling the bobbin, the bearing point is broken and the wooden shaft of the skewer is sometimes shattered; it is one of the objects of my invention to provide the lower or bearing end of the skewer with a device which will prevent such injury to the skewer when a loaded skewer is accidentally dropped.

Another objection to the common form of skewer is that by reason of, the fact that it is usually tenoned at its lower end and screwed into a socket in the pointed head, the stafi' of the skewer is not only weakened but is insecurely fastened in the head; it is a further object of this invention to obviate this objection.

A further objection to the common form of skewer is that the pointed head is usually made of wood, and it has been found that this material is so light in weight that occasionally a skewer will jump or be pulled out of the cup bearing in which the point of the head rests; a further object of the invention is to obviate this drawback, as more fully hereinafter set forth.

In the drawing Figure 1 is a side elevation of a skewer provided with my improved point;

Fig. 2 is a vertical sectional view of the lower end of the skewer;

Fig. 3 is a view similar to Fig. 2 with the parts disassembled, in position to be assembled;

Fig. at is a transverse section on the line 4l of Fig. 2; and i Fig. 5 is a view similar to Fig. 3, showing the socket wedge formed integral with the head.

Referring to the drawings annexed by reference characters, a designates the usual wooden staff of the skewer, and Z), the pointed head thereof, the latter being made of metal and being provided in its upper side with a socket for the reception of the lower end of the staff. This socket is enlarged downwardly, and, in order to spread the inserted end of the staff to lock it permanently in the socket, an upwardly-tapering conical wedge c is employed, this wedge, when the parts are assembled, bearing against the bottom of the socket and being, by the insertion of the staff, forced up into the end of the staff, to thus spread the lower end sufliciently to enlarge it to fit against the downwardly-tapering wall of the socket. In this way, a permanent rigid coupling is i made between the head and the staff without weakening the staff and without employing glue or other fastening devices of an inse cure nature. This form of connection between the staff and the head is made feasible by employing metal for the head, as the metal is sufficiently strong to prevent the forcible spreading of the lower end of the stafl from splitting the head, as would be likely to be the case if the head were made of wood or other material of slight strength.

Instead of making the wedge 0 separate from the head, it may be cast integral there with, as shown in Fig. 5. The head is provided with an annular flange (Z to support the bobbin, and the upper part of the head is rounded off to fit within the lower end of the bobbin, or is otherwise shaped. The lower part of the head is tapered down- .wardly to form the integral metal point f.

of the usual -bearing cup. The metal head also serves to prevent injury to the point '7 or the skewer staffl' in case a loaded skewer is accidentally dropped to the mfioor -point downwardly, thereby doing away with another material source of trouble with this type of device.

A- disadvantage witlnthe present Wooden head is that it gathers lint, thus resulting in occasionally breaking the thread and loss of. time re uired for vcleaning the i accumulated lint rom the head; this disadvantage is; entirely dqneawaynwith by employing a metal head, in View of the=factthatuthe surface of the metal is too smooth for the lint'to adhere to.

1 Having thus described invention; What EI elaim-is: r 1 l a In a skewer, a Wooden stafi; an all-metal "head provided With a downwardly-enlarged socket in its upper side adapted to fit the staff at-itsupper end; anda Wedgershaped device in; thehottom of the socket entering the lower end of the stafi to spread the same to fit the enlarged portion ,ofqthesoeket.
